摘要：针对垃圾渗滤液的氨氮、COD、难降解物质浓度高等特点,开发了磷酸铵镁沉淀法(MAP)脱氮-厌氧/好氧生物处理-混凝组合工艺处理垃圾渗滤液的新技术,研究了不同单元的作用及影响处理效果的因素。实验结果表明:高浓度垃圾渗滤液经组合工艺处理后,其COD、BOD5、NH3-N、E 260(紫外260 nm处吸光度,代表难降解有机物)的去除率分别为97.5%、99.2%、87.2%、75.3%。
A multi-stage wastewater treatment process was developed for treating high strength sanitary landfill leachate. Magnesium ammonium phosphate was employed in the first stage precipitation treatment to remove a major portion of the ammonia nitrogen present in the leachate; low oxygen/aerobic biological treatment in mixed reactors was then performed to remove biodegradable organic pollutants ; coagulation and flocculation treatment was performed at the last to produce a dischargeable final effluent. In the test case, COD was reduced from 10 300 to 256 mg/L and that BOD was reduced from 3700 to 28mg /L.
